Nvidia RTX 4090 Founders Edition Review

For our temperature testing, we measure the peak GPU core temperature under load. A reading under load comes from running Metro Exodus Enhanced Edition for 30 minutes.

We'd expect solid thermal performance from any Nvidia Founders Edition card, and certainly one this gargantuan, so it's good to see the GPU temperature peaked at just 70C during a prolonged stress test in Metro Exodus Enhanced Edition. The hot spot hit 78C, too, well within safe limits, and we also logged the GDDR6X memory junction temperature at a peak of 84C. I look forward to testing a range of partner cards in the coming days to see how they compare!
